What if your parent died and you suddenly discovered that everything they'd said about themselves, and about you, was untrue? "Requiem" is part psychological thriller - the story of a young woman, who, in the wake of her mother's death, sets out to learn the truth about herself, even to the point of unravelling her own identity. But it is also a subtle tale of the supernatural that avoids giving easy answers, playing instead on uncertainty, mystery and ambiguity.Writer Kris Mrksa says: "Requiem is the show I've always wanted to make. To be making it with the team at New Pictures, and for the BBC, a network that I so greatly admire, really is a dream come true."Willow Grylls and Charlie Pattinson, Executive Producers for New Pictures, say: "We are delighted to be given the opportunity to work with the brilliant writer Kris Mrska on this bold and distinctive series for BBC One.
